Qubed
- Delivering cutting-edge characterization infrastructure for quantum device materials
- An integrated platform enabling high-frequency, cryogenic, thermal, and optical characterization
- Defining rigorous evaluation benchmarks for quantum materials — driving supply chain readiness
Quantum Component Characterization Services
Realizing large-scale quantum computers demands high-performance components — from wiring and amplifiers to connectors and beyond. Establishing a reliable supply chain for these quantum materials requires both a robust evaluation infrastructure and clearly defined benchmarks.
Qubed is a characterization platform designed to assess the high-frequency, cryogenic, thermal, and optical properties of materials and components for quantum computers — lowering the barrier for diverse technology companies to enter the quantum industry.

High-Frequency Component Characterization
- Precise component evaluation in a simulated quantum computing environment using a tandem refrigerator
- Calibrated microwave measurements across 4K to 300K temperature ranges via high-frequency switching
- S-parameter measurements and time-domain analysis up to 26.5 GHz
- Simultaneous multi-port evaluation with up to 8-port high-frequency measurement capability

Additional Measurement Solutions
- High-frequency material parameter evaluation at cryogenic temperatures
- Characterization of magnetic, thermal, and other physical properties
- Proprietary quantum component evaluation methods currently in development

Dilution Refrigerators & Qubit Control Systems
- Experimental infrastructure for quantum device research
- A scalable equipment lineup tailored to the size of target devices
- Large-scale systems supporting up to 1,000 qubits
Cryogenic Evaluation Testbed
Characterizing superconducting qubits and similar devices requires ultra-low-temperature environments and high-speed microwave control systems. Access to such infrastructure and expertise can be a significant barrier for new entrants.
Qubed provides a fully equipped experimental environment — including dilution refrigerators and qubit control systems — to support the quantum ecosystem through collaboration across industry, academia, and government.
